IMPROVEMENT IN HORSE POWERS, j

GRORGR EIOHRNSRRR, OF WATERLOO, ILLINOIS. Letters Patent No.' 60,159, dated December 4,1866.

SPECIFICATrON.

TO ALL WHOM IT MAY GONCERN:

Be it known that I, GEORGE EICHENSER, of Waterloo, in the county of Monroe, and State of Illinois, have invented a new and useful Horse Power; and I do hereby declare that the following is a full and exactdescription' thereof. i

The nature of my invention is, firstly, in the use of a stationary but adjustable centre shaft, around which the parts in motion revolve; said moving parts consist principally'of a drum frame composed of segments, supported on caster-wheels, all said parts being iiexihly joined, said drum frame `being again flexibly joined by arms with a central collar revolving on the centre shaft. VAs it is the object of said drum frame to act as drivingpulley to a band or belt through which poweris to be transmitted, the general shape thereof is hereby determined moreover, as I apply the animal power to the arms connecting'said drum with the centre collar, inside, therefore, of said drum, I arrange said drum in segments, as aforesaid,lwhich may bedisconnected in such wise as to admit the animal or animals giving the power to theI proper positions in the interior.

To enable those skilled in the arts to malte and use my said improved machine, I will now describe its detail construction and,V application, referring herein to the accompaning drawings, andto the letters Vof reference marked thereon, of which similar letters indicate similar parts. Of said drawingsi Figure 1 is a general plan, showing in red lines one of the drum segments opened for the passage of the` horse, die.

Figure 2 is a central vertical sectional elevation. Ilconstruct Of any econoi'nical material, such as wood Or castiron, the `centre box, A, which forms the support for the centre shaft, B, Varound which all moving parts revolve; said shaft, B, stands vertically, and is at its lower end supported in the head, b, which is arranged to slide in proper ways, of the box, A; this sliding` v motion of b is regulated by a screw-shaft, al, which is made to move horizontally by the scrlew-nut, a, which, on being turned by a handle, a3, and being prevented from motion otherwise, causes the screw-shaft to move horizontally, thereby moving the head, b, in the ways or guide-slots of the box, A; thus` it will be seen that the centre shaft, B, is made to move horizontally, thereby causing all parts connected therewith properly to perform said motion. The collar or hub, C, surrounds B, resting on a collar, b, thereof; said collar, C, turns loosely around B, and receivesl in its radial arms the arms or spokes, D, and these connect with a ring drum or frame,

E, The arms, D, are secured in C by the horizontal bolt-rods, c, thus allowing the outer ends of said arms to 'vibratein a vertical direction g said parts, B and C, are usually of metal, whereas the arms, D, will'economically be of wood. It will then be seen that the ring frame or drum, Vlil, is compelled'to revolve aboutB as a centre. or the further support and guidance of E, I arrange the caster-wheels, F, The animal power is attached to a devis, G, secnred'to the arms, D, within the frame, E; said clevis is arranged to receive the draught ring or hook of the single` or double tree of this usual harnessings in any 'of three parts, g, g, and g2, thereby accommo- 'dating this attachment to the height of the animal, and to the levels of the ground, Sto. One pin, g3, secures the hook or ring aforesaid, in either of its positions, to the clevis, and thereby to the arm, D then the power, being applied to the arms, D, will cause the frame, E, to revolve about B. As it will, however, usually be necessary to pass the animal for the attachment thereof Vthrough the circuit of the ring, E, this is, therefore, as well as for the convenience of transportation as well as togive flexibility to said ring, made of segments, e. Usually eachsegment, e, is supported on two casters, F, the shaft of Vthe caster passing vertically through the body of the segment and permitting the segmentto lift and otherwise Inove in tho vertical direction prescribedliy its connection with the arms, D, and the connection thereof with the collar, C. Touconnect any two adjoining segments, e, I use a joint piece, (usually wrought `iron,) el, mortised in the body of one of said pieces and secured. hamm said piece, el, passes into a proper mortise of the other piece, and a pin, e2, secures the same; by withdrawing said pin said connection is easily opened. The same joint piece, e1, connects with la mortise in the arm, D, and a pin, di, here secures this connection by withdrawing this pin this connection is easily broken.` Owing to this arrangement, when it is'necessary` to pass an animal to the insideiof the rmg'frame, E, Iccan easily, by withdrawing the pins, e2, at each enel of the contiguous segment, e, and. withdrawing onepm, all, then cause this Asegment to moveV radially about the other di, as a centre,` ca thesegment to assume the position fully shown in red lines, iig. 1. When :the animal power source hash attached, and the ring frame, P, been completed, a driving belt 01- band, H, is passed around the Aouter crcmi enceof E, thuscausing to act as drivin gpulley to said belt, and by means of said belt, H, transmitting th power to anypoint desired.

N ow, as by the handle, as, and screw-shaft, al, 8vo., the centre shaft may be moved horizontally, and as the trainsmission of power by H is in s horizontal direction, the belt, H, can be tightened or otherwise adjusted by seid adjusting mechanisms, as, a2, al, to., before mentioned. I As was steted, the vertical shafts of the oesters pase through the body of each segment, e they pass-also above the same, thereby permitting the band, H', to ostoh and guide thereon in case the same slips oikfrom the outer rimof E; in a similar manner the belt is guided below E on the easter shafts.` Thel animals within the circumference of E are thus protected against the belt, H. The easter-Wheels, F, may run on n track or on the usual surface of the earth. To aeoommodste all inequalities of surface, which 'cause a vibratory orirregu'lar movement of parts, I have, as above stated, arranged the said rim drum, E, in segments,'and joinedthe' same eXibly to 4the arms, D moreover, these are joined flexibly to the coller, C. Again, the segments may move vertically upon the 'ester shafts to e'ect said adjustment.

Having thusfully described my invent-ion, what I claim, isv i l. The arrangement of the shaft B for horizontal adjustment, thereby tightening the driving-belt H,

`substantially as set forth.

2. The fiexible joint of the parts() und D, es set forth.' Y

3. 'The arrangement of the drum E in sections, e, and' their combination with each other and with the 'arme D, as set forth. i 4. The arrangement of the supporting casters F, and their combination with thesegment e, as set fort 5. The caster shaft as a guide for thebelt -H after it has slipped, substantialy as set forth.
